Abstract
A base station includes: a MIMO precoding section () for converting transmission data addressed to a mobile station to two data streams that respectively correspond to two reception antennas included in the mobile station, by performing MIMO precoding on the transmission data; a weight calculating section for calculating a transmission weight to be used for forming a directivity pattern directed toward each of the two reception antennas; and a weighting/combining section () for generating two combined data streams that are to be supplied to the respective antennas (-and-), by weighting each of the two data streams with the transmission weight calculated with respect to the reception antenna of the mobile station that corresponds to the data stream, and combining the two weighted data streams for each of the antennas (). The two combined data streams are respectively transmitted from the antennas (-and-).
